I'll be watching this for your BII tank set-up. I plan to do something similar on the 86 street truck I'm building, and am looking for all the info (pictures too) I can find on doing it. What you doing for a bed, stock ranger or custom bed. Also do you have a body lift, and how do you plan to route the filler?
Very interested to see what kind of clearance you have between that tank and the hitch you built.
